Curriculum Standards:
In any ecosystem, organisms and populations with similar requirements for food, water, oxygen, or other resources may compete with each other for limited resources, access to which consequently constrains their growth and reproduction. - DCI-MS-LS2.A.2
Growth of organisms and population increases are limited by access to resources. - DCI-MS-LS2.A.3
Plants, algae (including phytoplankton), and many microorganisms use the energy from light to make sugars (food) from carbon dioxide from the atmosphere and water through the process of photosynthesis, which also releases oxygen. These sugars can be used - DCI-MS-LS1.C1
Organisms, and populations of organisms, are dependent on their environmental interactions both with other living things and with nonliving factors. - DCI-MS-LS2.A.1
Within individual organisms, food moves through a series of chemical reactions in which it is broken down and rearranged to form new molecules, to support growth, or to release energy. - DCI-MS-LS1.C2
Substances are made from different types of atoms, which combine with one another in various ways. Atoms form molecules that range in size from two to thousands of atoms. - DCI-MS-PS1.A.1

Title: Interactive Science Introduction to Chemistry for Realize
STEMQuest, Labs, STEM, and Program Resources
STEMQuest
Hot and Cool Chemistry Quest Kick-Off
Curriculum Standards: Substances react chemically in characteristic ways. In a chemical process, the atoms that make up the original substances are regrouped into different molecules, and these new substances have different properties from those of the reactants. The total number of each type of atom is conserved, and thus the mass does not change. Some chemical reactions release energy, others store energy. Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred. Gather and make sense of information to describe that synthetic materials come from natural resources and impact society. Develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved. Undertake a design project to construct, test, and modify a device that either releases or absorbs thermal energy by chemical processes. The changes of state that occur with variations in temperature or pressure can be described and predicted using these models of matter. Develop a model that predicts and describes changes in particle motion, temperature, and state of a pure substance when thermal energy is added or removed.

Structure and Properties of Matter PE-MS-PS1-4 PEA
Curriculum Standards: A system of objects may also contain stored (potential) energy, depending on their relative positions. Temperature is a measure of the average kinetic energy of particles of matter. The relationship between the temperature and the total energy of a system depends on the types, states, and amounts of matter present. Develop a model to describe that when the arrangement of objects interacting at a distance changes, different amounts of potential energy are stored in the system. Apply scientific principles to design, construct, and test a device that either minimizes or maximizes thermal energy transfer. Plan an investigation to determine the relationships among the energy transferred, the type of matter, the mass, and the change in the average kinetic energy of the particles as measured by the temperature of the sample. Motion energy is properly called kinetic energy; it is proportional to the mass of the moving object and grows with the square of its speed. Construct and interpret graphical displays of data to describe the relationships of kinetic energy to the mass of an object and to the speed of an object. The changes of state that occur with variations in temperature or pressure can be described and predicted using these models of matter. Develop a model that predicts and describes changes in particle motion, temperature, and state of a pure substance when thermal energy is added or removed. A solution needs to be tested, and then modified on the basis of the test results in order to improve it. There are systematic processes for evaluating solutions with respect to how well they meet criteria and constraints of a problem. There are systematic processes for evaluating solutions with respect to how well they meet the criteria and constraints of a problem. Sometimes parts of different solutions can be combined to create a solution that is better than any of its predecessors. Models of all kinds are important for testing solutions. Undertake a design project to construct, test, and modify a device that either releases or absorbs thermal energy by chemical processes. Evaluate competing design solutions for maintaining biodiversity and ecosystem services. Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem. Analyze data from tests to determine similarities and differences among several design solutions to identify the best characteristics of each that can be combined into a new solution to better meet the criteria for success.

Curriculum Standards: For any pair of interacting objects, the force exerted by the first object on the second object is equal in strength to the force that the second object exerts on the first, but in the opposite direction (Newton's third law). All positions of objects and the directions of forces and motions must be described in an arbitrarily chosen reference frame and arbitrarily chosen units of size. In order to share information with other people, these choices must also be shared. Gravitational forces are always attractive. There is a gravitational force between any two masses, but it is very small except when one or both of the objects have large mass--e.g., Earth and the sun. Forces that act at a distance (electric, magnetic, and gravitational) can be explained by fields that extend through space and can be mapped by their effect on a test object (a charged object, or a ball, respectively). Apply Newton's Third Law to design a solution to a problem involving the motion of two colliding objects. Plan an investigation to provide evidence that the change in an object's motion depends on the sum of the forces on the object and the mass of the object. Construct and present arguments using evidence to support the claim that gravitational interactions are attractive and depend on the masses of interacting objects.

Curriculum Standards: The temperature of a system is proportional to the average internal kinetic energy and potential energy per atom or molecule (whichever is the appropriate building block for the system's material). The details of that relationship depend on the type of at Motion energy is properly called kinetic energy; it is proportional to the mass of the moving object and grows with the square of its speed. In any ecosystem, organisms and populations with similar requirements for food, water, oxygen, or other resources may compete with each other for limited resources, access to which consequently constrains their growth and reproduction. Similarly, predatory interactions may reduce the number of organisms or eliminate whole populations of organisms. Mutually beneficial interactions, in contrast, may become so interdependent that each organism requires the other for survival.

Curriculum Standards: Food webs are models that demonstrate how matter and energy is transferred between producers, consumers, and decomposers as the three groups interact within an ecosystem. Transfers of matter into and out of the physical environment occur at every level. D Develop a model to describe the cycling of matter and flow of energy among living and nonliving parts of an ecosystem. Organisms, and populations of organisms, are dependent on their environmental interactions both with other living things and with nonliving factors. In any ecosystem, organisms and populations with similar requirements for food, water, oxygen, or other resources may compete with each other for limited resources, access to which consequently constrains their growth and reproduction. Ecosystems are dynamic in nature; their characteristics can vary over time. Disruptions to any physical or biological component of an ecosystem can lead to shifts in all its populations. Analyze and interpret data to provide evidence for the effects of resource availability on organisms and populations of organisms in an ecosystem. Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations. Growth of organisms and population increases are limited by access to resources. Natural selection leads to the predominance of certain traits in a population, and the suppression of others. Adaptation by natural selection acting over generations is one important process by which species change over time in response to changes in environmental conditions. Traits that support successful survival and reproduction in the new environment become m Construct an explanation based on evidence that describes how genetic variations of traits in a population increase some individuals' probability of surviving and reproducing in a specific environment. Use mathematical representations to support explanations of how natural selection may lead to increases and decreases of specific traits in populations over time. The chemical reaction by which plants produce complex food molecules (sugars) requires an energy input (i.e., from sunlight) to occur. In this reaction, carbon dioxide and water combine to form carbon-based organic molecules and release oxygen. Plants, algae (including phytoplankton), and many microorganisms use the energy from light to make sugars (food) from carbon dioxide from the atmosphere and water through the process of photosynthesis, which also releases oxygen. These sugars can be used Construct a scientific explanation based on evidence for the role of photosynthesis in the cycling of matter and flow of energy into and out of organisms.

Bonding Super Heroes Scenario-Based Act
Curriculum Standards: Substances are made from different types of atoms, which combine with one another in various ways. Atoms form molecules that range in size from two to thousands of atoms. Gases and liquids are made of molecules or inert atoms that are moving about relative to each other. Substances react chemically in characteristic ways. In a chemical process, the atoms that make up the original substances are regrouped into different molecules, and these new substances have different properties from those of the reactants. The total number of each type of atom is conserved, and thus the mass does not change. Motion energy is properly called kinetic energy; it is proportional to the mass of the moving object and grows with the square of its speed. A system of objects may also contain stored (potential) energy, depending on their relative positions. Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred. Gather and make sense of information to describe that synthetic materials come from natural resources and impact society. Develop a model that predicts and describes changes in particle motion, temperature, and state of a pure substance when thermal energy is added or removed.

Develop a model to describe that when the arrangement of objects interacting at a distance changes, different amounts of potential energy are stored in the system.
Catching the Waves Scenario-Based Act
Curriculum Standards: A system of objects may also contain stored (potential) energy, depending on their relative positions. Temperature is a measure of the average kinetic energy of particles of matter. The relationship between the temperature and the total energy of a system depends on the types, states, and amounts of matter present. Energy is spontaneously transferred out of hotter regions or objects and into colder ones. When light shines on an object, it is reflected, absorbed, or transmitted through the object, depending on the object's material and the frequency (color) of the light. The path that light travels can be traced as straight lines, except at surfaces between different transparent materials (e.g., air and water, air and glass) where the light path bends. A wave model of light is useful for explaining brightness, color, and the frequency-dependent bending of light at a surface between media. Develop a model to describe that when the arrangement of objects interacting at a distance changes, different amounts of potential energy are stored in the system. Apply scientific principles to design, construct, and test a device that either minimizes or maximizes thermal energy transfer.

Help! I'm Trapped Under Here! Scenario-Based Act
Curriculum Standards: For any pair of interacting objects, the force exerted by the first object on the second object is equal in strength to the force that the second object exerts on the first, but in the opposite direction (Newton's third law). All positions of objects and the directions of forces and motions must be described in an arbitrarily chosen reference frame and arbitrarily chosen units of size. In order to share information with other people, these choices must also be shared. Gravitational forces are always attractive. There is a gravitational force between any two masses, but it is very small except when one or both of the objects have large mass--e.g., Earth and the sun. Forces that act at a distance (electric, magnetic, and gravitational) can be explained by fields that extend through space and can be mapped by their effect on a test object (a charged object, or a ball, respectively). Apply Newton's Third Law to design a solution to a problem involving the motion of two colliding objects. Plan an investigation to provide evidence that the change in an object's motion depends on the sum of the forces on the object and the mass of the object. Construct and present arguments using evidence to support the claim that gravitational interactions are attractive and depend on the masses of interacting objects. Conduct an investigation and evaluate the experimental design to provide evidence that fields exist between objects exerting forces on each other even though the objects are not in contact.

Curriculum Standards: For any pair of interacting objects, the force exerted by the first object on the second object is equal in strength to the force that the second object exerts on the first, but in the opposite direction (Newton's third law). All positions of objects and the directions of forces and motions must be described in an arbitrarily chosen reference frame and arbitrarily chosen units of size. In order to share information with other people, these choices must also be shared. Gravitational forces are always attractive. There is a gravitational force between any two masses, but it is very small except when one or both of the objects have large mass--e.g., Earth and the sun. Forces that act at a distance (electric, magnetic, and gravitational) can be explained by fields that extend through space and can be mapped by their effect on a test object (a charged object, or a ball, respectively). Apply Newton's Third Law to design a solution to a problem involving the motion of two colliding objects. Plan an investigation to provide evidence that the change in an object's motion depends on the sum of the forces on the object and the mass of the object. Construct and present arguments using evidence to support the claim that gravitational interactions are attractive and depend on the masses of interacting objects.

Curriculum Standards: The total number of each type of atom is conserved, and thus the mass does not change. Develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved. Each pure substance has characteristic physical and chemical properties (for any bulk quantity under given conditions) that can be used to identify it. Gravitational forces are always attractive. There is a gravitational force between any two masses, but it is very small except when one or both of the objects have large mass--e.g., Earth and the sun. Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred. Gather and make sense of information to describe that synthetic materials come from natural resources and impact society. Construct and present arguments using evidence to support the claim that gravitational interactions are attractive and depend on the masses of interacting objects. Variations in density due to variations in temperature and salinity drive a global pattern of interconnected ocean currents.

Curriculum Standards: Substances are made from different types of atoms, which combine with one another in various ways. Atoms form molecules that range in size from two to thousands of atoms. Gases and liquids are made of molecules or inert atoms that are moving about relative to each other. Substances react chemically in characteristic ways. In a chemical process, the atoms that make up the original substances are regrouped into different molecules, and these new substances have different properties from those of the reactants. The total number of each type of atom is conserved, and thus the mass does not change. Motion energy is properly called kinetic energy; it is proportional to the mass of the moving object and grows with the square of its speed. A system of objects may also contain stored (potential) energy, depending on their relative positions. Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred. Gather and make sense of information to describe that synthetic materials come from natural resources and impact society. Develop a model that predicts and describes changes in particle motion, temperature, and state of a pure substance when thermal energy is added or removed. Develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved. Construct and interpret graphical displays of data to describe the relationships of kinetic energy to the mass of an object and to the speed of an object.

What Is Matter Made Of?
Curriculum Standards: Substances are made from different types of atoms, which combine with one another in various ways. Atoms form molecules that range in size from two to thousands of atoms. Gases and liquids are made of molecules or inert atoms that are moving about relative to each other. Substances react chemically in characteristic ways. In a chemical process, the atoms that make up the original substances are regrouped into different molecules, and these new substances have different properties from those of the reactants. The total number of each type of atom is conserved, and thus the mass does not change. Motion energy is properly called kinetic energy; it is proportional to the mass of the moving object and grows with the square of its speed. A system of objects may also contain stored (potential) energy, depending on their relative positions. Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred. Gather and make sense of information to describe that synthetic materials come from natural resources and impact society. Develop a model that predicts and describes changes in particle motion, temperature, and state of a pure substance when thermal energy is added or removed. Develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved. Construct and interpret graphical displays of data to describe the relationships of kinetic energy to the mass of an object and to the speed of an object. Develop a model to describe that when the arrangement of objects interacting at a distance changes, different amounts of potential energy are stored in the system. In a liquid, the molecules are constantly in contact with others; in a gas, they are widely spaced except when they happen to collide. In a solid, atoms are closely spaced and may vibrate in position but do not change relative locations.

The changes of state that occur with variations in temperature or pressure can be described and predicted using these models of matter. Develop a model that predicts and describes changes in particle motion, temperature, and state of a pure substance when thermal energy is added or removed. Some chemical reactions release energy, others store energy. Undertake a design project to construct, test, and modify a device that either releases or absorbs thermal energy by chemical processes.

Curriculum Standards: Develop a model to describe the cycling of water through Earth's systems driven by energy from the sun and the force of gravity.
Transfer of Heat Student Tutorial
Curriculum Standards: A system of objects may also contain stored (potential) energy, depending on their relative positions. Temperature is a measure of the average kinetic energy of particles of matter. The relationship between the temperature and the total energy of a system depends on the types, states, and amounts of matter present. Energy is spontaneously transferred out of hotter regions or objects and into colder ones. Develop a model to describe that when the arrangement of objects interacting at a distance changes, different amounts of potential energy are stored in the system. Apply scientific principles to design, construct, and test a device that either minimizes or maximizes thermal energy transfer. Plan an investigation to determine the relationships among the energy transferred, the type of matter, the mass, and the change in the average kinetic energy of the particles as measured by the temperature of the sample.

Develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved. Gases and liquids are made of molecules or inert atoms that are moving about relative to each other. In a liquid, the molecules are constantly in contact with others; in a gas, they are widely spaced except when they happen to collide. In a solid, atoms are closely spaced and may vibrate in position but do not change relative locations. Solids may be formed from molecules, or they may be extended structures with repeating subunits (e.g., crystals). The changes of state that occur with variations in temperature or pressure can be described and predicted using these models of matter. Develop a model that predicts and describes changes in particle motion, temperature, and state of a pure substance when thermal energy is added or removed. Some chemical reactions release energy, others store energy. Undertake a design project to construct, test, and modify a device that either releases or absorbs thermal energy by chemical processes.

Each pure substance has characteristic physical and chemical properties (for any bulk quantity under given conditions) that can be used to identify it. Gases and liquids are made of molecules or inert atoms that are moving about relative to each other. In a liquid, the molecules are constantly in contact with others; in a gas, they are widely spaced except when they happen to collide. In a solid, atoms are closely spaced and may vibrate in position but do not change relative locations. Solids may be formed from molecules, or they may be extended structures with repeating subunits (e.g., crystals). The changes of state that occur with variations in temperature or pressure can be described and predicted using these models of matter. Develop a model that predicts and describes changes in particle motion, temperature, and state of a pure substance when thermal energy is added or removed.

How Is Mass Conserved During a Chemical Reaction? Key Concept Summary
Curriculum Standards: A system of objects may also contain stored (potential) energy, depending on their relative positions. Temperature is a measure of the average kinetic energy of particles of matter. The relationship between the temperature and the total energy of a system depends on the types, states, and amounts of matter present. Develop a model to describe that when the arrangement of objects interacting at a distance changes, different amounts of potential energy are stored in the system. Apply scientific principles to design, construct, and test a device that either minimizes or maximizes thermal energy transfer.

Solids may be formed from molecules, or they may be extended structures with repeating subunits (e.g., crystals). The changes of state that occur with variations in temperature or pressure can be described and predicted using these models of matter. Develop a model that predicts and describes changes in particle motion, temperature, and state of a pure substance when thermal energy is added or removed. Some chemical reactions release energy, others store energy. Undertake a design project to construct, test, and modify a device that either releases or absorbs thermal energy by chemical processes. The total number of each type of atom is conserved, and thus the mass does not change. Substances are made from different types of atoms, which combine with one another in various ways. Atoms form molecules that range in size from two to thousands of atoms. Each pure substance has characteristic physical and chemical properties (for any bulk quantity under given conditions) that can be used to identify it.

How Is Mass Conserved During a Chemical Reaction? Key Concept Summary
Curriculum Standards: A system of objects may also contain stored (potential) energy, depending on their relative positions. Temperature is a measure of the average kinetic energy of particles of matter. The relationship between the temperature and the total energy of a system depends on the types, states, and amounts of matter present. Develop a model to describe that when the arrangement of objects interacting at a distance changes, different amounts of potential energy are stored in the system. Apply scientific principles to design, construct, and test a device that either minimizes or maximizes thermal energy transfer. Plan an investigation to determine the relationships among the energy transferred, the type of matter, the mass, and the change in the average kinetic energy of the particles as measured by the temperature of the sample.

The total number of each type of atom is conserved, and thus the mass does not change. Some chemical reactions release energy, others store energy. Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred. Gather and make sense of information to describe that synthetic materials come from natural resources and impact society. Develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved. Undertake a design project to construct, test, and modify a device that either releases or absorbs thermal energy by chemical processes.

Curriculum Standards: There are systematic processes for evaluating solutions with respect to how well they meet the criteria and constraints of a problem. Apply scientific principles to design, construct, and test a device that either minimizes or maximizes thermal energy transfer. Evaluate competing design solutions for maintaining biodiversity and ecosystem services. Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem. Analyze data from tests to determine similarities and differences among several design solutions to identify the best characteristics of each that can be combined into a new solution to better meet the criteria for success.

Ionic Bonds Wkbk Lesson
Curriculum Standards: Each pure substance has characteristic physical and chemical properties (for any bulk quantity under given conditions) that can be used to identify it. Forces that act at a distance (electric, magnetic, and gravitational) can be explained by fields that extend through space and can be mapped by their effect on a test object (a charged object, or a ball, respectively). Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred. Gather and make sense of information to describe that synthetic materials come from natural resources and impact society. Conduct an investigation and evaluate the experimental design to provide evidence that fields exist between objects exerting forces on each other even though the objects are not in contact.

Curriculum Standards: The geologic time scale interpreted from rock strata provides a way to organize Earth's history. Analyses of rock strata and the fossil record provide only relative dates, not an absolute scale. Construct a scientific explanation based on evidence from rock strata for how the geologic time scale is used to organize Earth's 4.6-billion-year-old history.
